TRUCK-BAR.

SPECIFICATION forming part of Letters Patent No. 388,770, dated August 28, 1888.

Application filed July 1 1886.

To all whom it may concern.-

Be it known that I, JOSEPH H. FISHER, a citizen of the United States, and a resident of Deerfield, in the county of Lake and State of Illinois, have invented new and useful Improvements in TruclcBnrs, of which the following is a specification, reference being had to the accompanying drawings, illustrating the invention, in which- Figure I is a perspective representation of the truck-bar embodying my invention; Fig. II, an elevation of the truck end of the bar and the roller therein; Fig. III, an under side view of the truck end, the handle being broken off, as at Fig. II.

The purpose of thisinvention is to provide a bar which will serve the purpose of the ordinary bar for raising bodies, and also serve the purpose of a truck for moving articlessuch as timber and stone-bodily after they are raised. The bar is adapted to open and move car-doors where the pressure of the grain is so great thereon as to prevent them from being moved by ordinary means. The instrument is to be made of metal, and for most purposes steel is preferable.

D represents the the prongs or jaws, when required, in

handle of the bar, and B O the latter being formed, hammer-claw shape for Renewed July 2, 1888. Serial No. 278,857.

drawing spikes or nails; but for handling stone and timber a single jaw will serve the purpose as well as the claws or prongs and cost less. Therefore I manufacture both styles. Ahandle, H, is formed on the end of the bar, as a convenient and necessary hand-hold when the device is to be used as a truck. E represents a roller, which is placed in a vertical slot in the bar and secured so as to rotate by means of a pivot-bolt, S, as more clearly shown at Fig. II, where the side of the device is broken away to show the construction. The roller projects down from the bar far enough to form a fulcum, that the bar may be used as a lever and elevate a body without moving it horizontally. To attain the best results in construction the bar must be made quite heavy at the point of connection with the roller, that it may have a uniform resisting force.

Having thus descr'. ed my invention, I claim and desire to secure by Letters Patent- A new tool or truck-bar consisting of the bar part D, the prongs or jaws B G, and the roller E, pivoted in the bar so as to project below the same and form a fulcrum, as specified.
